Today biomass burning is accepted to be an important source of many trace gases affecting atmospheric chemistry (Crutzen et al., 1979; Cofer et al., 1988a; Radke et al., 1988; Crutzen et al., 1990). Despite its global significance and in contrast to fossil fuel use, where…

Fires in tropical savannas are a principal source of emissions to the atmosphere, but there are few studies of retention in ash and residual plant mass following natural fires. Estimates of carbon and nitrogen emissions to the atmosphere from biomass burning have relied largely…

Previous studies of the effects of heating on soil hydrophobicity have been conducted under free availability of oxygen. Under fire, however, soils may be deprived of oxygen due to its consumption at the heat source and inadequate replenishment in the soil. In the present study…
